The AirTAC SDA100X45S Compact Cylinder | 100mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø100mm bore and 45mm stroke, PT3/8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA100X45S is a double-acting, single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. Utilizing a riveted assembly that merges the barrel, rear cover, piston, and rod, this unit saves substantial mounting depth compared to conventional round-body actuators. At 100 mm bore, it generates 3927 N of push force and 3524.9 N of pull force at 0.5 MPa, driven through a PT3/8 air port.
This specific model includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves, enabling precise end-of-stroke detection. The 32 mm piston rod features a female M18x1.5 thread for secure load coupling. Deceleration at the 45 mm stroke limits is handled by a fixed NBR bumper, which absorbs impact energy but is not an adjustable air cushion or a locking mechanism.

Provides the robust 3927 N push force required to eject heavy formed metal panels from a 200-ton stamping press bed, utilizing the short 45 mm stroke to minimize machine intrusion.
Handles vertical lifting of 200 kg industrial gearbox assemblies during palletizing operations, where the compact riveted body conserves vertical overhead space in tight robotic cells.
Delivers high breaking force to separate stubborn injection molding halves, with the built-in -S magnet triggering solid-state switches to confirm full mold release before robotic extraction.
Selecting this 100 mm bore actuator involves evaluating your force margins and spatial constraints. If your application requires less force, stepping down to the SDA80 provides 2513.3 N at 0.5 MPa, which may better suit medium-duty tasks while saving physical space. As the largest standard option, there is no larger bore in this series.
When ordering, confirm the 100 mm bore, 45 mm stroke, PT3/8 port, female M18x1.5 rod thread, and the required -S magnet for sensor tracking. Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the piston near the stroke end and cannot hold a load. For vertical or suspended loads, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 100 mm bore double-acting cylinder outputs 3927 N push and 3524.9 N pull at 0.5 MPa, and 5497.8 N push at 0.7 MPa. The theoretical maximum push is 801 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, handles a proof pressure of 1.5 MPa, and functions in temperatures from -20 to +70 C at speeds of 30-500 mm/s.
It relies on a fixed NBR bumper at each end to decelerate the piston, which is not a field-adjustable air cushion. For high-speed or high-energy cycles, you should add an external shock absorber. Furthermore, it does not hold position naturally; if air is lost, the piston drifts. You must use an external rod lock or pilot-operated check valve to suspend loads safely.
